Four people have been arrested after police carried out a raid on a suspected large-scale cannabis grow.

Durham Police executed a magistrate's warrant at an address on Main Street in Ferryhill shortly after 9.30am this morning (November 8).

Officers found a "substantial haul of cannabis plants" covering over four floors of the building and have made four arrests.

Police said they are likely to be on the scene for a considerable time due to the size and complexity of the property.
